"When I saw photos of the red helium balloons tied to stormwater drains in Sydney I was furious,” he said.

“When balloons end up in the ocean they float and get swallowed by seabirds, dolphins, whales and turtles.”

Hollywood executives are holding out hopes the latest adaption of Stephen King’s terrifying novel IT will save box office profits, after it suffered its worst US summer in a decade.

A report by Variety claims that US cinemas experienced 14.6 percent drop in the number of people going to the movies, compared to the same time in 2016, making only $3.8 billion in ticket sales.

Breakout winter and spring hits – including Beauty and the Beast and Get Out – have been this year’s saving grace, and New Line’s IT is expected to pick up the summer slack.

The much-anticipated horror film about an immortal, shapeshifting entity named Pennywise who appears every 27 years to feed on kids is expected to make approximately $60 million in the US during its opening weekend.

The movie features a character called Pennywise who often takes the appearance of clown. (IT Movie) ()
